Dynamic Load Balancing Library
DLB is a dynamic library designed to speed up HPC hybrid
applications (i.e., two levels of parallelism) by improving the load balance of the outer
level of parallelism (e.g., MPI) by dynamically redistributing the computational resources
at the inner level of parallelism (e.g., OpenMP). at run time. This dynamism allows DLB to
react to different sources of imbalance: Algorithm, data, hardware architecture and
resource availability among others.
Lend When Idle LeWI (Lend When Idle) is the algorithm
used to redistribute the computational resources that are not being used from one process
to another process inside the same shared memory node in order to speed up its execution.
Dynamic Resource Ownership Manager
DROM (Dynamic Resource Ownership Manager) is the algorithm used to manage the CPU affinity of a process running a shared memory programming model (e.g., OpenMP)
